EDUCATIONAL APPLIANCE.

Specification of Letters Patent.

Patented'May 16, 1916.

' Application filed February 19, 1916. Serial No. 73,385.

To all whom it mag "concern Be it known that I, ALBERT S. JOHNSON, a citizen of the United States, residing at Bassett, in the county of Mississippi and State of Arkansas, have. invented certain new and useful Improvements in Educational Appliances, of which the following is a specification, reference being had to the accompanying drawings] 7 i This invention relates to certain improve-v ments in educational appliances and it is anobject of the invention to provide a novel and improved device of this general character whereby the relation between the earth and sun at differing periods of the year' may vide a novel and improved device of this 7 general character including a rotatably supported member indicating the earth and having members detachably engaged therewith to denote the differences in the pe-,

V ripheral speed of the earth and to indicat the character of vegetation at c'fiiferlng altitudes.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved appliance whereby certain important advantages are attained and the device is rendered simpler, less expensive and other wise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein- Figure 1 is a view in elevation with a portion broken away of an educational appliance constructed in accordance with an embodiment of my invention; Fig. 2 is a sec-- tional view taken substantially on the line 2-2 of Fig. l with the member representing the sun in a position different from that shown in Fig. 1; Fig. 3 is a'view partly in elevation and partly in section illustrating a globe constructed in accordance with a modified form of my invention; Fig. 4c is an elevational view illustrating a still further form of globe as herein included; andFig. 5 is a view, detached, in elevation, illustrating a member coacting with either of the globes disclosed in Figs. 3 and 4 for indicating the character of vegetation at differing altitudes.

As disclosed in the'accompanying drawings, l denotes a suitable base having eX- tending upwardly therefrom thealined up irights 2, the upper extremities 3 ofthe uprights '2 being disposed in predetermined diverging planes. Movably engaged with the uprights 2 is the bar 4 which is also removably directed through a globe G which is capable of free rotation about the bar 4.

The upper portions of the diverging extremities 3 are tied or connected by the arcuate bar 5 provided with the longitudi nally disposed slot 6, and coacting with the bar 5 is the member 7 which is to be construed as the equivalent of the sun, and said member 7 is'provided with an extension 8 directed through the slot 6 in the bar 5 andv with which coacts the winged nut 9, whereby the member 7 may be fixed at differing positions longitudinally of the bar 5.. The portions 3 are also tied or connected by the plate 10 positioned above the bar 5 and also of arcuate formation and arranged substantially concentric to the bar 5, and the forward face of the plate 10 is provided with a plurality of graduations, as indicated at 11, whereby the position of the member 7 at opposite sides of the longitudinal center of the bar 5 or the equator line on the globe G may be readily and conveniently determined in accordance with the necessities of practice.

12 denotes a shield substantially semicircular in form which is pivotally suptice the upper or straight edge of the shield 12 is adapted to be held at right angles to the center of the member 7 as determined by the extension 8, whereby it will clearly indicate the portions of the globe G in darkness. The upper portion of the shield 12 is provided with the oppositely directed arms 17 whereby the requisite rotation may be imparted to the shield 12, as is thought to be self-evident.

The globe G disclosed in Fig. 1 is divided to indicate the several Zones as is well known, while in Fig. 3, the globe G is provided with the meridians and in Fig. 4 the globe G has produced thereon parallels.

As disclosed in Fig. 3, the globe G is provided with a plurality of openings or recesses 18 in predetermined positions and of any desired number, while the globe G is also provided with the recesses or perforations 23.

As disclosed in Fig. 3, 19 denotes members of substantially pyramidal form having their bases provided with the extensions or fingers 20 adapted to be inserted within the openings 18 or 23, whereby upon rotating the globe, it will be fully demonstrated that the globe has greater peripheral speed at the equator than at points at opposite sides thereof.

In Fig. 5 a pyramidal member 21 is dis closed which is adapted to be engaged within the recesses 18 or 23, and said member 21 is divided into sections, as indicated at 22, whereby the character of vegetation at difi'erent altitudes may be demonstrated, it being understood that suitable emblems within the sections may be employed as best meets the requirements of practice.

It is to be observed that the upright 14 or more particularly the pivoted bolt 15 is positioned at a point to represent the equator and is therefore positioned in a vertical plane intersecting the longitudinal center of the bar 5 and plate 10.

I find it of advantage to interposc between the uprights 2 the brace 2- l substantially semi-circular in form and which has its intermediate portion in engagement with the base 1.

From the foregoing description, it is thought to be obvious that an appliance constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

1. An educational appliance comprising a base, uprights carried thereby, a globe adapted to be rotatably supported by the uprights, a third upright positioned at a point to one side of the globe and intermediate the first named uprights, and a shield rotatably supported by the last named upright, said shield being substantially semicircular in form.

2. An educational appliance comprising a base, uprights carried thereby, a globe adapted to be rotatably supported by the uprights, a third upright positioned at a point to one side of the globe and intermediate the first named uprights, a shield rotatably supported by the last named upright, said shield being substantially semicircular in form, and means for maintaining the shield in its various adjustments.

8. An educational appliance comprising a base, uprights carried thereby, a globe adapted to be rotatably supported by the uprights, a third upright positioned at a point to one side of the globe and intermediate the first named uprights, a shield rotatably supported by the last named upright, said shield being substantially semicircular in form, an arcuate bar supported by and between the first named uprights and positioned above the globe, and a member supported by the bar and adjustable longitudinally thereof.

4. An educational appliance comprising a base, uprights carried thereby, a globe adapted to be rotatably supported by the uprights, a third upright positioned at a point to one side of the globe and intermediate the first named uprights, a shield rotatably supported by the last named up right, said shield being substantially semicircular in form, an arcuate bar supported by and between the first named uprights and positioned above the globe, a member supported by the bar and adjustable longitudinally thereof, and an arcuate plate supported by and between the uprights and above the bar, a face of said plate being provided with graduations.

5. An educational appliance comprising Vided with recesses, and a, member seatable' within a. recess.

In testimony whereof I hereunto aflix my signature in the presence of two Witnesses.

ALBERT S. JOHNSON.
